Ok, then how mambo would allow you to create pages (lyrics) and search for terms. Apart from some skinning you shouldn't need the programmer.
Or you could use a customised directory script where you categorise by Style / Artist then list the song titles, clicking a title takes you to a full page showing the lyrics.
I'm sure there are a million and one ways of doing this it's down to you to make a list of what you want to be able to do then the programmer can go through it and refine it with you.
I just Googled on "script for lyrics site" and came up with a good number of scripts, this
http://www.harlandscripts.com/lyric/ was just one of them.
